Waller Field 4/6--LITTLE TINAMOU, FORK-TAILED PALM-SWIFT, SULPHURY FLYCATCHER, RUFOUS-BREASTED WREN, + MASKED YELLOWTHROAT

No pictures here. Kim and a local guide, Rudy, took us first to the Aripo Savanna to search for and eventually find a MASKED YELLOWTHROAT, a warbler that look almost exactly like our Common Yellowthroat, sans the gray line around the mask, and then over to Waller Field, an abandoned World War II American Air Force base. Here, moriches palms attract some specialty birds like SULPHURY FLYCATCHER, which we found, and Moriches Orioles, which we did not. We also heard the extremely difficult to see LITTLE TINAMOU, saw FORK-TAILED PALM-SWIFTS glide overhead, and heard another skulking bird, RUFOUS-BREASTED WREN. It was raining on and off, a continuation of the rain from the earlier in the day. Happily, the rain stopped as we were leaving for the livestock station where Kim had planned an evening of owls and nightjars. On the way out the trees were filled with what we approximated to be 300 Black Vultures. Even though they're harmless, there is something unsettling about massive congregations of these scavengers.
